NREL’s Vehicle Ancillary Loads Reduction team has been working with industry to try to reduce fuel consumption from air conditioning in cars and trucks. The use of ventilated seating is one way to cut air conditioning, and recent research shows that it works.
"If all passenger vehicles had ventilated seats, we estimate that there could be a 7.5 percent reduction in national air-conditioning fuel use. That translates to a savings of 522 million gallons of fuel a year," said John Rugh, project leader for NREL’s Vehicle Ancillary Loads Reduction Project.
W.E.T. Automotive Systems Ltd. provided NREL with ComfortCools® seats for testing. Each seat contains two fans that pull air from the seat surface and out from underneath the seat. General Motors currently offers this ventilated seat as an option for the Cadillac STS.
Using its suite of thermal comfort tools and subjective test data, NREL measured improvement in human thermal sensation for the ventilated seats and the potential for a 7 percent reduction in air-conditioning compressor power.
NREL developed its thermal comfort tools to help the automotive industry design smaller and more efficient climate-control systems in vehicles. The tools consist of a one-of-a-kind thermal comfort manikin called ADAM (ADvanced Automotive Manikin)—which actually breathes and sweats—along with a physiological model and psychological model. Linked together, these tools assess comfort in a transient, nonhomogeneous environment, unlike other commonly used models based on steady-state, uniform environmental data.
NREL is the U.S. Department of Energy’s (DOE) primary national laboratory for renewable energy and energy efficiency research and development. NREL is operated for DOE by Midwest Research Institute and Battelle.

At the LASYS 2018, from June 5th to 7th, the Laser Zentrum Hannover e.V. (LZH) will be showcasing processes for the laser material processing of tomorrow in hall 4 at stand 4E75. With blown bomb shells the LZH will present first results of a research project on civil security.
At this year's LASYS, the LZH will exhibit light-based processes such as cutting, welding, ablation and structuring as well as additive manufacturing for...
There are videos on the internet that can make one marvel at technology. For example, a smartphone is casually bent around the arm or a thin-film display is rolled in all directions and with almost every diameter. From the user's point of view, this looks fantastic. From a professional point of view, however, the question arises: Is that already possible?
At Display Week 2018, scientists from the Fraunhofer Institute for Applied Polymer Research IAP will be demonstrating today’s technological possibilities and...
So-called quantum many-body scars allow quantum systems to stay out of equilibrium much longer, explaining experiment | Study published in Nature Physics
Recently, researchers from Harvard and MIT succeeded in trapping a record 53 atoms and individually controlling their quantum state, realizing what is called a...

A team led by Austrian experimental physicist Rainer Blatt has succeeded in characterizing the quantum entanglement of two spatially separated atoms by observing their light emission. This fundamental demonstration could lead to the development of highly sensitive optical gradiometers for the precise measurement of the gravitational field or the earth's magnetic field.
The age of quantum technology has long been heralded. Decades of research into the quantum world have led to the development of methods that make it possible...
